Why a protein shake after lifting might make you eat less
Whey protein consumption after resistance exercise reduces energy intake at a post-exercise meal

After working out, drinking a protein shake made people eat less at their next meal—not because they felt fuller, but because they ate slower and the shake felt thicker and creamier.

When people consume 30% of their daily calories from protein without restricting food intake, they eat fewer calories overall and lose body fat.
Young, trained men who drink a whey protein shake 5 minutes after lifting weights eat about 430 kJ less at their next meal than when they drink a carbohydrate shake with the same calories, due to slower eating and different texture, without feeling hungrier or fuller.
After consuming whey protein following resistance exercise, people eat more slowly, reducing their energy intake by 16.5 kJ per minute on average, regardless of how hungry or full they feel.
Whey protein drinks that are thicker and creamier lead to lower food intake after a workout, and these texture features have a stronger effect on how much people eat shortly after exercise than the protein, fat, or carbohydrate content of the drink.
In trained individuals, eating whey protein after weight training and consuming slightly fewer calories does not reduce muscle growth, as long as protein intake and resistance training remain high.
